The eggs of Giraud's Tyrant-bird are normally of a narrow oval 

 shape and exhibit a varying amount of gloss. They are white, 

 marked with spots and small blotches of purplish red, lilac-red, and 

 lavender. In the majority of specimens, the markings are more 

 dense at the broad end and form an irregular cap, but in others 

 they are evenly distributed over the entire shell. Examples 

 measure from -85 to 1-02 in length, and from -67 to -71 in breadth.
